Abstract: A mobile communication system, a user equipment in the mobile communication system, a control program thereof, and a synchronization establishment determination method in the mobile communication system are provided to more adequately perform the synchronization establishment determination even when transmitted waves of multiple systems become approximately out of phase while diversity transmission is performed in the mobile communication system using W-CDMA(Wideband-Code Division Multiple Access). A synchronization establishment determination method is executed when a dedicated channel is set, such as when the communication of user equipment is started. When the synchronization establishment determination method is started, a control unit determines whether a result of normal synchronization establishment determination is that the synchronization is capable of being established or not on the basis of a fact that BER(Bit Error Rate) of TPC(Transmit Power Control) bits is lower than a TPC-BER threshold(S1). At step S1, if the result is not determined whether the synchronization is capable of being established in the normal synchronization establishment determination, the control unit determines whether or not a phase difference of a common channel of a 0-system and a 1-system is within a phase difference threshold range(S2). At step S2, if it is determined whether the phase difference of the common channel of the 0-system and the 1-system is within the phase difference threshold range or not, the control unit determines whether or not the reception quality of the common channel is higher than a reception quality threshold(S3). The control unit 25 determines whether a determination result in the synchronization establishment determination process is that the synchronization is capable of being established(S4), and terminates the process. The control unit determines whether the determination result in the synchronization establishment determination process is that the synchronization is not capable of being established"(S5), and terminates the process.
